The connection structure of the prefabricated shear wall of the utility model is simple in structure, low in cost and easy to implement;

[0004] Although the above patent ensures better connection effect by filling with grouting material, the grouting sleeve connection technology is complicated and requires extremely high accuracy of the reserved wall sleeve and steel bars. At the same time, the grouting sleeve connection technology requires high technical level of construction workers, which leads to greater construction difficulty in actual projects. In addition, a large amount of cement and mortar is consumed in the connection and fixation through concrete, which increases the burden of mortar resources and is not conducive to the sustainable development of society. The above patent cannot effectively and conveniently handle the installation of prefabricated shear walls, which leads to the problem of low installation efficiency of prefabricated shear walls.

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1-7 As shown, the embodiment of the utility model provides a prefabricated shear wall structure, including a wall panel 1 and a connecting plate 3, the inner surface of the connecting plate 3 is provided with an assembly mechanism 2, and the assembly mechanism 2 includes a cavity 201, an insertion rod 205 and a positioning bolt 209;

[0032] The cavity 201 is formed in the inner surface of the upper and lower ends of the rear side of the connecting plate 3 . The front side of the cavity 201 is fixedly connected with a hard spring 202 , and the rear side of the hard spring 202 is fixedly connected with a movable plate 203 .

[0033] By setting up the assembly mechanism 2, the wall panel 1 is clamped on both sides of the connecting plate 3 for preliminary fixation, and then the pull rod 204 is pulled to drive the movable plate 203 to move outward through the pull rod 204, and drive the hard spring 202 to stretch outward, so that the hard spring 202 is deformed, and the deformation of the hard spring 202 drives the plug rod 205 to move outward. When the plug rod 205 is aligned with the inner cavity of the insertion hole 206, the pull rod 204 is released, and the hard spring 202 is deformed again due to the loss of force, driving the plug rod 205 to be inserted into the inner cavity of the insertion hole 206, and then the first connecting hole 207 and the second connecting hole 208 are connected by the positioning bolt 209 to complete the assembly of the wall panel 1, so that the installation of the prefabricated shear wall is effectively and conveniently processed, thereby improving the installation efficiency of the prefabricated shear wall.

[0034] Example 2

[0035] In one embodiment, a pull rod 204 is fixedly connected to the rear side of the movable plate 203, an insertion rod 205 is fixedly connected to the front side of the movable plate 203, insertion holes 206 are provided at the upper and lower ends of the outer side of the wall panel 1, the front end of the insertion rod 205 is inserted into the inner cavity of the insertion hole 206, a plurality of first connection holes 207 are provided on the outer side of the wall panel 1 and on the inner side of the insertion hole 206, a plurality of second connection holes 208 are symmetrically provided on the outer surface of the connecting plate 3, and the first connection hole 207 and the second connection hole 208 are threadedly connected by positioning bolts 209.

[0036] By setting the pull rod 204, the movable plate 203 can be easily pulled, and by setting the socket 206, the socket 206 can be plugged into the plug rod 205. By setting the positioning bolt 209, the connection between the wall panel 1 and the connecting plate 3 can be made more stable.

[0037] Example 3

[0038] In one embodiment, a protective mechanism 4 is provided on the surface of the wall panel 1, and the protective mechanism 4 includes a base layer 401, a first functional layer 402 and a second functional layer 403. The first functional layer 402 is arranged on the outside of the base layer 401, and the second functional layer 403 is arranged on the outside of the first functional layer 402. The first functional layer 402 includes a modified hydroxyl acrylic resin 4021 and a polyurethane waterproof coating 4022. The modified hydroxyl acrylic resin 4021 is arranged on the outside of the base layer 401, and the polyurethane waterproof coating 4022 is arranged on the outside of the modified hydroxyl acrylic resin 4021. The second functional layer 403 includes a polyvinyl chloride resin coating 4033 and an epoxy resin coating 4034. The polyvinyl chloride resin coating 4033 is arranged on the outside of the polyurethane waterproof coating 4022, and the epoxy resin coating 4034 is arranged on the outside of the polyvinyl chloride resin coating 4033.

[0039] By setting the protective mechanism 4, the problem of poor protective function of the existing wall panel 1 can be solved. By setting the modified hydroxyl acrylic resin 4021 and the polyurethane waterproof coating 4022, the color wall panel 1 can be made resistant to high temperatures. By setting the polyvinyl chloride resin coating 4033 and the epoxy resin coating 4034, the wall panel 1 can be made wear-resistant.

[0040] When the utility model is working: firstly, the wall panel 1 is clamped on both sides of the connecting plate 3 to complete the preliminary fixation of the wall panel 1, and then the pull rod 204 is pulled to drive the movable plate 203 to move outward through the pull rod 204, and drive the hard spring 202 to stretch outward, so that the hard spring 202 is deformed, and the insertion rod 205 is driven to move outward through the deformation of the hard spring 202. When the insertion rod 205 is aligned with the inner cavity of the insertion hole 206, the pull rod 204 is released, and the hard spring 202 is deformed again due to the loss of force, driving the insertion rod 205 to be inserted into the inner cavity of the insertion hole 206, and then the first connecting hole 207 and the first connecting hole 207 are aligned with the first connecting hole 206 through the positioning bolt 209. The second connecting hole 208 is connected to complete the assembly of the wall panel 1, so that the installation of the prefabricated shear wall is effectively facilitated, thereby improving the installation efficiency of the prefabricated shear wall. When the wall panel 1 encounters wear in the working environment, the first functional layer 402 of the modified hydroxyl acrylic resin 4021 and the polyurethane waterproof coating 4022 is set, which can effectively play a wear-resistant role for the wall panel 1. When the wall panel 1 encounters a high temperature environment in the working environment, the second functional layer 403 of the polyvinyl chloride resin coating 4033 and the epoxy resin coating 4034 is set, which can effectively play a high temperature resistance role for the wall panel 1, thereby extending the service life of the wall panel 1.
